Once you enter the cave you can find the wolf marker just behind the small waterfall on the left, then head right the drop down to the lower level and fight any endrega warriors and workers here.

The boots diagram requires a bit of manual traveling/swimming, as it's in a cave to the east of the keep and not near any signposts. Once it's killed you'll find the diagram on the small altar like table near the hidden tunnel. Head in but be careful as an Earth Elemental is in the main room. The gauntlets diagram is found at Iron Mine. When you exit the cave, there will be harpies on the road back, if they didn't spawn there previously. Although not requried, there is interesting commentary by Geralt when you examine various things in the cave, and you can also find Trial of the Grasses registry tome. From the area where you can come across the first table apparatuses and mutagen bottles, go just past the one on the left and you'll see the chest behind the stalagmites (you've gone too far if you reach the small set of stairs). Head inside and follow the path, where along the way you'll come across a few nekker warriors and a devourer. The trousers diagram is found in a cave northwest of Kaer Morhen and north of the Bastion.

The easiest way to get these marked on the map is to buy the heavily faded notes from Hierarch Square's armorer.
